      In 1981, the University of Arizona's Department of Plant Pathology and Office of Arid Lands Studies (Arizona Remote Sensing Center) began a joint research project to map and estimate concomitant reductions in yield caused by Phymatotrichum root rot (PRR) using simulated orbital and airborne imagery. With support from the U.S. Department of Agriculture, Cooperative States Research Service and NASA-Ames Research Center, substantial progress has been made in improving estimates of yield. While work to date has been limited to cotton, future studies will include additional crops and other diseases.
